Description

[Detailed Description of the Invention] [Technical Field] This invention relates to the structure of a lamp guard for a lighting fixture.

[Background technology]

In the conventional example shown in Fig. 1, the lamp replacement work is performed by completely removing the lamp guard 1 from the shade 2, replacing the lamp 3, and then attaching the lamp guard 1 to the shade 2 again. It's on. However, it is troublesome to remove and reinstall the lamp guard 1, and the work is done at a high place, which not only results in poor workability overall, but also makes it difficult to hold the lamp guard 1 in one hand while holding it in the other. Because the work involved ramp 3, there was a risk of falling. Also, the guard is supported by a spring,
Some were hinged (for example, Jikko 38
−28095, Jitko No. 44-28709, Jitko No. 57−
No. 10407), but both required the use of both hands when replacing the lamp, posing the same danger as above.

[Purpose of invention]

The purpose of this invention is to provide a structure for a lamp guard for a lighting device that allows lamp replacement work at high places to be carried out efficiently and safely.

[Disclosure of invention]

The structure of the lamp guard of this lighting fixture is as follows:
A roughly rattupa-shaped shade with a lamp located in the center,
a lamp guard which covers the front side of the lamp of the shade and whose base end is rotatably supported by a horizontal shaft located further back of the shade than the front side of the lamp; and a spring that urges the lamp guard to a state where both ends of the tip of the lamp guard are locked to the inner surface of the shade, and both ends of the tip of the lamp guard are locked to the inner surface of the shade, The lamp is characterized in that a gap is formed between the middle part of the tip and the inner surface of the shade to allow insertion of the lamp base.

According to the structure of this invention, the lamp guard can be opened by inserting the lamp base into the gap and pulling the tip of the lamp guard against the spring, so that the lamp can be efficiently lit with only one hand holding the lamp. can be exchanged. Therefore, the body can be stably supported with the extra hand, and safety can be ensured, for example, when working at heights. Also, since the horizontal axis of the lamp guard is located further back than the front of the lamp, it is easy to open the lamp guard.

An embodiment of this invention will be explained based on FIGS. 2 to 4. The lamp guard 11 is made by assembling fine wire material and bending it into a dogleg shape, and its base end is pivotally supported at a position on the back side of the inner surface of the shade 13 by a hinge 12 having a horizontal axis. . 14 is the position of the shade 13 sandwiching the hinge 12 and the lamp guard 1
The spring is an example of a coil spring stretched across the lamp guard 11 and the lamp guard 11.
is lifted and energized against its weight. Note that the spring 14 may be a rubber string or a helical spring. Due to the biasing force of the spring 14, both ends 11a, 11a of the tip of the lamp guard 11 come into contact with the inner surface of the shade 13, and their positions are regulated. This posture is a protective posture for the lamp 15, and the lamp guard 11
A gap 17 with a size sufficient to hook the base 16 of the lamp 15 is provided between the middle part of the tip of the lamp 15 and the inner surface of the shade 11.

As shown in FIG. 4a, insert the cap 16 of the lamp 15 held in one hand into the gap 17, hook the cap 16 onto the lower end of the lamp guard 11, and then move the lamp 15 in the direction of the arrow X. The lamp guard 11 swings in the direction of arrow Y around the horizontal axis of the hinge 12 against the force of the spring 14. From this state, the lamp 15 is inserted into the shade 13 and attached to the appliance body 18 as shown in FIG. 4b. During this time, lamp guard 1
1 is maintained in its open position by contact with the hand holding the lamp 15. If the lamp 15 is removed after installation, the lamp guard 11 automatically returns to its original lamp protection position by the force of the spring 14. That is, the lamp 15 can be installed with one hand.

Since the lamp guard 11 is held by the shade 13, there is no need to hold it with the other hand, and that hand must be used to keep the worker's posture safe by holding a ladder, touching a wall, pillar, etc. It can be useful for

The lamp 15 can also be removed with one hand. In other words, put one hand into the gap 17, swing the lamp guard 11 in the direction of the arrow Y, and push the lamp 1
5 from the instrument body 18 and then just pull it out downward. After being pulled out, the lamp guard 11 is naturally returned to its original position by the spring 14.

[Effect of idea]

According to the structure of the lamp guard of the lighting device of this invention, the lamp guard can be opened by inserting the lamp base into the gap and pulling the tip of the lamp guard against the spring, so that the lamp can be held. You can efficiently replace the lamp with just one hand. Therefore, the body can be stably supported with the extra hand, and safety can be ensured, for example, when working at heights. Furthermore, since the shaft of the lamp guard is located inward from the front of the lamp, there is an effect that the lamp guard can be opened easily.
